+name: memtier_benchmark-session-caching-string-100k-sessions
+description: |
+  Runs memtier_benchmark to simulate a session caching workload for a SaaS application.
+  This benchmark focuses exclusively on **string-based session storage**, where each session
+  is stored in Redis as a serialized JSON string (`session:<id>`) containing fields like
+  user ID, timestamps, device info, and metadata (total ~400–600B).
+
+  The benchmark models a typical read-heavy cache usage pattern, with an approximate
+  **read:write ratio of 80:20**, reflecting session retrievals and infrequent updates.
+
+  Command groups:
+    - Session cache reads (`GET`): ~80%
+    - Session cache writes (`SET`): ~20%
+
+  To better approximate real-world access patterns, the benchmark uses a **Zipfian key distribution**
+  (`--command-key-pattern=Z`). This simulates **skewed access** where a small subset of sessions (hot keys)
+  receives a majority of reads — a common pattern in production workloads.
+
+  While Zipfian is technically a power-law distribution, it effectively mimics **Poisson-like behavior**
+  in large-scale systems, where access frequency is uneven but statistically predictable.
+  This access skew mirrors real-life scenarios such as:
+    - Frequently accessed or "sticky" user sessions
+    - Popular user accounts or active devices
+    - Hot caches for trending or recently used resources
+
+  Using Zipfian distribution allows this benchmark to capture **contention**, **cache pressure**, and
+  **read amplification** effects that occur in real SaaS applications under load.
